have you heard of the pythagorean theorem?

anonymous · Answer

No

mertsj · Answer

square the legs of the right triangle shown.  Add those numbers together.  Take the square root.  That will be the missing side of the triangle.  Then you can figure out which is greater and by how much.

anonymous · Answer

i dont know how to do any of that.

So calculus, I guess.  Because that is math.

15^2 + 20^2 = c^2            20^2 = 400     e square root to get the correct distance

anonymous · Answer

ugh but now what

mertsj · Answer

So the missing side is 20.  Now look at your picture.

mertsj · Answer

225+400= 625 and the square root of 625 is 25 so the missing side is 25.

anonymous · Answer

thank you so much so the answer is B .

mertsj · Answer

If he goes the long way that would be 15+20 or 35.  The short way is 25.  So if he goes the long way, it is 35-25 or 10 longer

mertsj · Answer

The answer is 10.  That is choice C
